To all whom t may concern.-

Be it known that- I, MICHAEL M. MOIN- 'rr1n:, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State ot' Ohio, have invented a certain new and useful Improvement in Vehicle-Springs,

of which the following is a full, clear, and exact description, reference being had to the aceompanying drawings.

This invention relates to vehicle springs which are suitable for carriages, wagons and automobiles; and it is characterized by the employment, for a complete spring, ot' two'spring sections, preferably of the leaf type; and the relative. strength and construction of the sections and the manner of connecting them to the vehicle are such that, when so connected, one section supports, unaidnd, the normal unloaded eight-.ot the vehicle and the other section comes into action as soon as any load is applied to the vehicle and assists the former section in sup porting the load thus placed on the vehicle.

The object and result of this construction are to give a better and easier movement to the vehicle alike when empty and when slib- ;ieeted to light or heavy loads.

Various forms ol" the invention are illustrated in the accompanying drawings, Fig' ures1,l, El and 4 being, respectively, elevations of different forms, all however, em-

bodying the doublespring idea referred to.

Figs. .r and 6 are `details in section on the lines 5w 5 and 6'-l3 of Figs. 1 and 2, respeetively.

Referring specifically to the drawings, G

indicates the frame oi" the.vehicle, to which are secured in a. suitable manner the ont,- riders or supporting arms T. AThe upper spring section, which will be designated for convenience of description the carrier spring, is indicated at- 8 and the lower spring section or load spring at 9t-he spring sections being of the leaf type and fasteued'toget'her at the middle by clips, in i The spring sections The tension ot the section' 8 is such that it supports. when in the position shown 1n iull lines in `thedrawings. the normal unloaded ,..weightot tin-vehicle body-thatis,the

` springseetion, if released, would rise to the position, say., indicated ,by the dotted lines S iiillig. l of the drawings, but when connected to the supporting arm the weightof the Vehicle body causes git' to take the position shown in full lines. The normal position of the sprinfr 9 that shown in full lines in the drawings-that is, in the position shown in the draufings. it supports no weight, the weight of the vehicle, asv stated above, being' entirely sustained by the spring section 8. If, however. the vehicle be leaded, the weightof t-he load is taken partly by the spring sec tion or load spring 9, or, in other words, the combined weight of the vehicle and loadv is taken by the two spring sections 8 and 9. The spring section t), or load spring, in all the modifications is provided with relai tively long. flexible ends, and the strength 70 and curvature otl the springsect'ions are dev terminedjn advance, according to the weight of the vehicle bodtx,y and vthe maximum load`` to be. supported by the spring sectionsso' that when the sections are applied and connect ed to ,the vehicle, the weight ot the'rehiele body will cause the carrier spring to ben-:l tio .the extent required 'for the att-ach-` ment of the arm T to the load spring tl without the necessity for deflecting thevl'at- 80 ter. The attachment of the springsections will be effected in various ways, as, shown in the drawings.

In Fig. 1. the spring sections have their ends curled to` -form eyes, .the ends 'of *thev upper spring' section being curled upwardly and the ends of the lowerspring section being curled downwardly, and the arms 7 are vconnected by shackle links 11 and 12 to the adjacent ends Aof spring sections 8 and t), by k90 means of pins 13. 14 and 15, pinsy 1.3 extendingr through the upper endsvof shackle links 11 and the eyes ofv spring section 8, pins 11 extending through the lower endsv of the sluiporting arm 7 and the pivotally supported ends of shackle links 11 and 12 and the pins 15 extending `through the lower ends of shackle links 1Q and the eyes of spring section t). Double links or shackles are used, as clearly shown in the sectional View, Fig. 5. l y

In" the form shown in Fig. 2, the ends .ofl the springscctions are left plain or flat 'and are slotted,vas at 1G, within and adjacent t0 the extreme ends thereof. Single links are used (indicated respect-ivob' at 11a and 12a). These links extend through the slots in the` end portions or1 the spring sections and each The rollers are carried by pins 13, 14, the

latter pin also serving to connect the snpporting arm i' Wdhthe links, the eye of the supporting arm being forked as indicated 'at Y, liig. G, to receive therebetn-'een the upper end of link 12R and the lower end oi link lll, the adjacent ends ot the links being halved and lapped where the pin extends through them betvveen the forks of the supporting arm, as clearly shown in Fig. (i. This construction is decidedly advantageous and allows a free and easy movement oiE the ends of the spring sections. Under ordinary slow movements of the spring ends, the rollers and links move together, the links occupying the same portions of the slots throughout the movements. Under sudden and severe shocks or blows, the rollers permit the ends of the spring sections to move relatively to the links, and a. free and easy nmvementI of the spring ends is thus provided under all conditions of use. A stop pin 12b is inserted in the loiver end of the link 12a to hold the same in proper relation to the. spring section 9.

The forms oflspring shown in Figs. l and 2, having` both ends fiexihly connected to the supporting arms, are adapted for use as rear springs of vehicles having radius rods.

In Fig. 8, the upper and lower spring7 sections 8 and 9 are connected to the supporting arms 7 by means of levers 1'1", which are pivoted intermediate of their ends to said su porting arms 7 by the pins 14. The ends 0ig spring section 8 are connected to the upper ends of these levers by means of pins 13 and the ends ofthe spring section 9 are provided'with scrolls 9a which extend dOWnwardly and are connected to the lower ends of the levers by pins 15. l

l In Fig. 4, the scroll ends of the kspring 'notion 9 are shown as connected to the pins it by means of which the links 111 are conihEcted to the arms 7 and the ends of the u per s ring" section 8 are connected by pins L b to t e upper ends of said links.

It will be noted that, in all of the modifications o my invention disclosed herein, the lower or load spring 9 is lighter than the upper or carrier spring 8 and has long flexible ends, said ends being provided by the absence of reinforcement for the upper pair of plates for a considerable portion of their length. i

The double springs herein described secure ease of riding under all conditions of the vehicle, Whether it be empty or whether it be under light or heavy loads. y
